God only knows how long you will live, how far life will take you, what path you will take, what arguements you will get into, where those arguements will lead you, or so on and so forth. So be thankful for today, be thankful for the family you have (no matter what is going on between you), be thankful for the friends you have, be thankful for the shelter over your head (no matter how small or worn it is), be thankful for every breath you take because everything you have it is a gift, not a given.
I am thankful for all of my Friends (online and off), Family (here and there), and Every breath that whatever god is up there gives me.
My final thought: BE THANKFUL! You'll never know when it will end.
